Try adding some air. I run my summer 235/45 Michelins at 34 psi. I had the same issue when the 225/45 General artic snows went on. Found that they really needed 38-40 psi and they are much better handling. They handled well enough for me to avoid a pickup truck cap that came straight at my windshield! Dove into the break down lane hugging the guardrail as the cap went by my side window! Damn, these tires are better than I expected!!
Made in Germany and the price is right!
